LIDOCAINE- LIDOCAINE OINTMENT LAKE ERIE MEDICAL DBA QUALITY CARE PRODUCTS LLC ---------- LIDOCAINE OINTMENT USP, 5% FOR TOPICAL USE ONLY RX ONLY DESCRIPTION Lidocaine Ointment 5% contains a local anesthetic agent and is administered topically. See INDICATIONS AND USAGE for specific uses. Lidocaine Ointment 5% contains lidocaine, which is chemically designated as acetamide, 2- (diethylamino) -_N_-(2,6-dimethylphenyl)-, and has the following structural formula: C H N O M.W. 234.34 Composition of Lidocaine Ointment 5%: acetamide, 2-(diethylamino)-_N_-(2,6-dimethylphenyl)-, (lidocaine) 5% in a water miscible ointment vehicle containing polyethylene glycols and peppermint oil. CLINICAL PHARMACOLOGY MECHANISM OF ACTION Lidocaine Ointment 5% effects local, topical anesthesia. The onset of action is 3-5 minutes. It is ineffective when applied to intact skin HEMODYNAMICS Excessive blood levels may cause changes in cardiac output, total peripheral resistance, and mean arterial pressure. These changes may be attributable to a direct depressant effect of the local anesthetic agent on various components of the cardiovascular system. PHARMACOKINETICS AND METABOLISM Lidocaine may be absorbed following topical administration to mucous membranes, its rate and extent of absorption depending upon the specific site of application, duration of exposure, concentration, and total dosage. In general, the rate of absorption of local anesthetic agents following topical application occurs most rapidly after intratracheal administration. Lidocaine is also well-absorbed from the gastrointestinal tract, but little intact drug appears in the circulation because of biotransformation in the liver. Lidocaine is metabolized rapidly by the liver, and metabolites and unchanged drug are excreted by the kidneys. Biotransformation includes oxidative N-dealkylation, ring hydroxylation, cleavage of the amide linkage, and conjugation. N-dealkylation, a major pathway of biotransformation, yields the metabolites monoethylglycinexylidide and glycinexylidide. Citiți documentul complet
